Description
Technical field
The utility model relates to a kind of draining pump motor in fluid machinery technical field, particularly a kind of water-cooled high-efficient energy-saving environment friendly stainless steel motor special for water pump.
Background technology
Pump motor is AC induction motor, industrial multiplex three phase electric machine, civilian large multiplex monophase machine.Blade is loaded onto in one end of motor, and blade rotary just drives water flow, just the same with electric fan, just electric fan rotates is drive gas flow and water pump drives liquid flow, large-scale industrial water pump is more piece water pump, and its blade divides several layers, and water is pumped up.A large amount of heats can be produced in the course of work of motor, motor temperature is caused to raise and burn out motor, so the useful life in order to extend motor, cooling process must be carried out to the motor in work, and present stage is water-cooled cooling to the main method that motor cools.
At present, market Water-cooling water pump motor adopts motor housing to install one deck outer barrel additional, utilizes motor-hollow axle or conduit circulation to carry out cooling water pump motor.The endoporus of incrustation scale blocking hollow shaft or conduit when motor-hollow axle or conduit are subject to pore size and use for a long time, easily cause motor inhomogeneous cooling even, time serious, motor-hollow axle or conduit are subject to the blocking of incrustation scale, motor is caused normally to cool, make motor temperature increase rapidly, burn out motor.The cooling of conventional water-cooled machine utilizes high pressure that is extraneous or water pump self that hydraulic pressure is entered cooled region, then water is being put into the low region of pressure.There is following defect in this setup: first, motor cooling position is in high pressure conditions all the time, on the overall structure of motor and running balance impact very large, cause motor rotation off-target operating point to run, and motor housing exists the pressure of water under high pressure, run dangerous; Secondly, motor bearings can not completely balancedly cool, and bearing easily damages; Finally, motor can not Homogeneous cooling, and cooling effect is poor, affects electric efficiency, and energy-saving effect is not obvious.
Utility model content
For the defect existed in existing Water-cooling water pump motor, the utility model provides a kind of water-cooled energy-efficient stainless steel motor.
To achieve these goals, technical solution adopted in the utility model is:
The energy-efficient stainless steel motor of a kind of water-cooled, comprise the body be arranged in cooling tank, the top of cooling tank is connected with fluid section, fluid section top is provided with delivery port, body is the double-layer shell structure comprising motor casing inner and outer wall, cooling duct between motor casing inner and outer wall is communicated with water inlet, and body is connected with the impeller be located in fluid section, and the periphery of impeller is provided with impeller set;
Described impeller comprises blade and upper and lower cover plates, and blade and upper and lower cover plates are structure as a whole by punching press assembly welding;
The height of the cooling duct between described motor casing inner and outer wall is 20mm;
Described water inlet is arranged on electric motor end cap position or is arranged on cooling tank sideway stance;
The material of described body is stainless steel.
The beneficial effects of the utility model: motor is fully immersed in water, motor temperature is by normal-temperature water Homogeneous cooling, and motor is stable, and efficiency improves 3%, and energy-saving effect is obvious; Noise during motor rotation is given shielding by water completely, runs noise lower, environmental protection more; Motor bearings is completely evenly cooled by normal-temperature water, and bearing extends one times useful life.
Accompanying drawing explanation
Fig. 1, structural representation of the present utility model.
Embodiment
The energy-efficient stainless steel motor of a kind of water-cooled, comprise the body 1 be arranged in cooling tank 2, the top of cooling tank 2 is connected with fluid section 4, fluid section 4 top is provided with delivery port 6, body 1 is the double-layer shell structure comprising motor casing inner and outer wall, cooling duct between motor casing inner and outer wall is communicated with water inlet 3, and body 1 is connected with the impeller 5 be located in fluid section 4, and the periphery of impeller 5 is provided with impeller set; Described impeller 5 comprises blade and upper and lower cover plates, and blade and upper and lower cover plates are structure as a whole by punching press assembly welding; The height of the cooling duct between described motor casing inner and outer wall is 20mm; Described water inlet 3 is arranged on electric motor end cap position or is arranged on cooling tank sideway stance; The material of body 1 is stainless steel.
In the course of work, current flow into cooling duct by water inlet, are cooled by motor, then discharge from delivery port after flowing through fluid section.Because cooling duct distance is enough, incrustation scale can not impact motor cooling, and motor is fully immersed in water simultaneously, cooling water circulation amount is large, and evenly, motor and bearing run completely under normal-temperature water state in flowing, motor external skin temperatures is in normal temperature state all the time, and cooling effect is obvious.And motor cooling water is always atmospheric pressure state, motor runs more steady; Cooling water is soaked motor in water completely, and the noise of motor rotation is given shielding by water, and noise is lower.Noise in operating is below 50 decibels.The beneficial effects of the utility model: motor is fully immersed in water, motor temperature is by normal-temperature water Homogeneous cooling, and motor is stable, and efficiency improves 3%, and energy-saving effect is obvious; Noise during motor rotation is given shielding by water completely, runs noise lower, environmental protection more; Motor bearings is completely evenly cooled by normal-temperature water, and bearing extends one times useful life.
Those ordinary skill in the art simply replace and change is all within this patent protection range.
